There is a way to add additional storage to your iOS or Android device that's both cheaper than paying the premium, and it's quick and simple, with no need to take your device to bits.

What you need is a Wi-Fi-enabled portable hard drive. There are two worth taking a look at.

While externally they look different, underneath the outer shell they're quite similar. Both have SSD storage, integrated Wi-Fi, and include rechargeable batteries -- and both come with applications for Android and iOS that you can download from the respective app stores.

You can store documents and photos, as well as storing and playing back music and video, all while the drive is safely tucked away in your pocket, bag or briefcase.

A iPad mini (64GB, Wi-Fi) will cost you $529, but you could buy the 16GB, Wi-Fi only for $329 and add an extra 64GB of storage -- storage that you can use and access from other devices -- all while saving $100.
